Jakob Stoklund Olesen 8289f78569 Remove the isMoveInstr() hook. 
llvm-svn: 108567

Jakob Stoklund Olesen 65306369ae Replace copyRegToReg with copyPhysReg for MSP430.

Stuart Hastings 0125b6410a Add a DebugLoc parameter to TargetInstrInfo::InsertBranch(). This 
addresses a longstanding deficiency noted in many FIXMEs scattered
across all the targets.

This effectively moves the problem up one level, replacing eleven
FIXMEs in the targets with eight FIXMEs in CodeGen, plus one path
through FastISel where we actually supply a DebugLoc, fixing Radar
7421831.

Dan Gohman 779c69bbc5 Add a DebugLoc argument to TargetInstrInfo::copyRegToReg, so that it 
doesn't have to guess.

Anton Korobeynikov ce52fd5f93 Add branch relaxation pass (shamelessly stolen from PPC).

Dan Gohman 047a767d74 Remove the target hook TargetInstrInfo::BlockHasNoFallThrough in favor of 
MachineBasicBlock::canFallThrough(), which is target-independent and more
thorough.
